DiskGem® is software for secure file transfer over SFTP.
DiskGem currently offers an easy to use, stable command-line user interface that supports parallel file transfers and other useful features. DiskGem will soon also support creating encrypted archives on the server which offer encryption of stored files as well as metadata obfuscation.
Download DiskGem for Linux and macOS.
Note: DiskGem currently works fine on Windows through the Windows Subsystem for Linux (WSL).
